Connie, directly behind, bumped into her.

“What’s the idea, Vevi McGuire?” she demanded. “You nearly made me fall into the water!”

Vevi spoke in an excited, hushed voice. “Connie, just see what is coming!”

She moved aside so that her little friend’s view would not be blocked. The barn doors had swung open, and now, clattering toward them, was a cart hauled by a huge dog.

“Well, did you ever!” exclaimed Connie, laughing in delight.

The little cart had two wheels. It was painted bright blue and held empty milk cans.

Hurrying on across the bridge, the two girls ran toward the dog. Even though he had no driver, he seemed to know exactly where he was supposed to go. At least he trotted toward the milk house farther down the canal.

“Hello, doggie,” Vevi called in a soft voice. “What’s your name?”

To her astonishment, the dog stopped and looked at her. He was a very large dog, but with a sad, kind face.

“Why, he’s friendly as anything!” Connie exclaimed.
